Does ANYONE have Cummins with engine brake?
From : mac davis
Q: after research here and on the rvforum it looks like several folks say that the engine brake would be nice or would help etc... but nobody seems to have one.. seems like if they were that good or that important there would be a lot of folks out there with them right im starting to feel that its not worth the hassle but im open to opinions.. mac .

john i took your reply below to mean the dodge dealer should be able to install the engine brake. is this correct im been recently pulling a small two horse bumper pull trailer and noticed the additional braking effort need when stopping even with the electric brakes on the trailer. thanks john reichert on mon 14 jun 2004 052600 gmt john mooney jamooney44@earthlink.net wrote tons of questions john! was it dealer installed yes. do you think it was worth the additional cost at the time late 2002 there was a special deal available for small business purchasers of rams and i was out-of-pocket only about $250. however dodge strongly recommends the exhaust brake if you are going to tow 10000# or more. i will be soon. it already makes a big difference for me when towing the little travel trailer i have now particularly when im in the rockies usually. so i can invision how much it will help with a real load. i really like having it and am glad i bought it. any problems with the engine or transmission that you think could be caused by the eb none whatsoever. however at the time it was only available with the 6-speed manual and that is what i ordered. rumor has it that it still is not compatible with the new auto transmission. i believe the problem is with locking up the torque converter in order for the exhaust brake to have something besides just atf to apply its retarding force against. drivers behind you have to be alert to the fact that you are slowing down sometimes rather rapidly without any brake lights coming on. many more im sure as the day we write that $40000 check gets closer.. any time. i have the jacobs on my 2003 and find it very useful even when not towing. any questions after research here and on the rvforum it looks like several folks say that the engine brake would be nice or would help etc... but nobody seems to have one.. seems like if they were that good or that important there would be a lot of folks out there with them right im starting to feel that its not worth the hassle but im open to opinions.. mac mac .

i have a bd exhaust brake on a 2001 6spd ho. i have had it about 30000 miles and believe it is the best money i have spent. i pull two different trailers first a 36 rv 5th wheel and travel through the rogers pass in british columbiacanada on a regular basis. the second is a 5th wheel to haul my tractors and other equipment. i have weighed as high as 22500 lbs gross. the exhaust brake holds the truck on the steepest grades. i generally do not use the service brakes until down to very slow speeds. the pads and linings on both the truck and the trailers show almost no wear at all and most important if i need the brakes in an emergency they are cold and will provide maximum stopping. it is a bit noisy but i have done no servicing nor have i had any problems with it. the manufacturer claims i think 190 bhp hold back at maximum. if you want other info let know. robby after research here and on the rvforum it looks like several folks say that the engine brake would be nice or would help etc... but nobody seems to have one.. seems like if they were that good or that important there would be a lot of folks out there with them right im starting to feel that its not worth the hassle but im open to opinions.. mac .

a real engine brake or jake brake designed by some guy named jacobs creates retarding power by modifing the valve timing on the fly opening the exhaust vavles just before combustion. this slows the engine because its using energy from the motion of the truck to compress the air/fuel in the cylinder but combustion is being produced to provide more power. an exhaust brake is usually mounted behind the turbo and has a large butterfly valve. when this is closed it produces backpressure in the whole system including the cylinders. different methods of getting the same result. also the exhaust brake isnt as loud as an engine brake. my exhaust brake just sounds like air rushing out of the pipes. andy youve got me there andy... whats a pacbrak and why would you have to swap engines .

mechanic told me just yesterday that there is an adjustment for this on my 93. is two bars that extend diagonally from near the transmission mount to the front wheel area. he said that to tighten the bolts that mount these bars in the rear wheel lift the front possibly two inches to match the rear as my front is lower than the rear also. -- from the desk of jesse a. harrington anyone have any ideas on how i can raise the frt end of my 00 dakota qc 2wd about 1 1/2-2 ive seen these spacer things in jc whitney and also these rubber boots that go on the end of the coil springs. just want to raise the frt to level it out with the rear. thanks. .

once you have something to force your torque converter locked and keep it that way youll be all set. i use a bd torqlok module. andy on mon 14 jun 2004 213626 gmt andy redac@verizon.net wrote i sure like the quieter part andy... the jakes on semis are so loud that a lot of places dont allow them.... i think that if they clear up the problems with having one with the automatic well add it to our shopping list.. .

close but not quite right. http//www.heavydutytrucking.com/2001/12/044a0112.asp the idea for retarders originated almost 50 years ago with clessie cummins the diesel pioneer. he had retired from cummins engine in indiana and moved to the west coast. there he became more aware of the need to allow big rigs to go downhill as efficiently as uphill. his answer was the engine compression brake and he took it to his old company - but was rebuffed. executives saw no need for it. but he found a taker for his patented device at of all companies jacobs manufacturing which was known for the jacobs chucks used to secure bits in power drills. a real engine brake or jake brake designed by some guy named jacobs creates retarding power by modifing the valve timing on the fly opening the exhaust vavles just before combustion. this slows the engine because its using energy from the motion of the truck to compress the air/fuel in the cylinder but combustion is being produced to provide more power. an exhaust brake is usually mounted behind the turbo and has a large butterfly valve. when this is closed it produces backpressure in the whole system including the cylinders. different methods of getting the same result. also the exhaust brake isnt as loud as an engine brake. my exhaust brake just sounds like air rushing out of the pipes. andy youve got me there andy... whats a pacbrak and why would you have to swap engines .
